Hi , I am having a problem for so long I believe some one can help me out.. I am using Windows XP 2000 service pack2. When ever I try to download any application file or any .exe file my system restarts automatically without giving me even one second to cancel the download, I tried to download it many time but every time PC restarts. I can not download any .exe file and any application for example I was trying to download the Google Earth but my PC restarts automatically. Kindly suggest if there is some problem with my Browser (Mozilla firefox) or if there is any specific setting in the browser or somewhere in the control Panel in my PC .. I have been facing this problem for a long time ..I also formatted my system many times but every time I face the same problem. Awaiting your suggestions/solutions. Umesh281
